Detailed explanation-1: -The splenic vein arises in the splenic hilum behind the tail of the pancreas and runs from left to right on the posterior surface of the pancreatic body. Union of the horizontal splenic vein and the vertical SMV forms the portal vein behind the neck of the pancreas.
Detailed explanation-2: -Portal annular pancreas is a rare pancreatic variant in which the uncinate process of the pancreas extends and fuses to the dorsal surface of the body of the pancreas by surrounding the portal vein.
Detailed explanation-3: -Pancreatic head: The head drains into the superior mesenteric vein (SMV). Body and the neck: The splenic vein drains these.
